Impact of Transplantation Timing on Renal Graft Survival Outcomes and Perioperative Complications.

Nighttime organ transplantation aims to decrease cold ischemia duration, yet conflicting data exists on its impact on graft function and perioperative complications. This multicenter TRANSPLANT'AFUF study including 2,854 patients, transplanted between 1 January 2011, and 31 December 2022, investigated nighttime kidney transplantation's impact (8:00 p.m.

Standardized one-day evaluation before urinary reconstructive surgery for neurogenic lower urinary tract dysfunction: Feasibility and impact on surgical strategy and care pathway.

Objectives: To describe a concept of standardized preoperative one-day evaluation before urinary reconstructive or diversion surgery for the treatment of neurogenic lower urinary tract (LUT) dysfunction, and to evaluate its feasibility and its impact on the care pathway.

Materials And Methods: All patients who underwent a one-day standardized evaluation before a urinary reconstructive or derivation surgery for the treatment of neurogenic LUT dysfunction between January 2017 and December 2021 in our institution were included. Data were collected retrospectively from standardized reports.

Nuclear Resonant Surface Diffraction of Synchrotron Radiation.

Nuclear resonant x-ray diffraction in grazing incidence geometry is used to determine the lateral magnetic configuration in a one-dimensional lattice of ferromagnetic nanostripes. During magnetic reversal, strong nuclear superstructure diffraction peaks appear in addition to the electronic ones due to an antiferromagnetic order in the nanostripe lattice. We show that the analysis of the angular distribution together with the time dependence of the resonantly diffracted x rays reveals surface spin structures with very high sensitivity.

miRNAs in ESC differentiation.

MicroRNAs (miRNAs) are small sequences of noncoding RNAs that regulate gene expression by two basic processes: direct degradation of mRNA and translation inhibition. miRNAs are key molecules in gene regulation for embryonic stem cells, since they are able to repress target pluripotent mRNA genes, including Oct4, Sox2, and Nanog. miRNAs are unlike other small noncoding RNAs in their biogenesis, since they derive from precursors that fold back to form a distinctive hairpin structure, whereas other classes of small RNAs are formed from longer hairpins or bimolecular RNA duplexes (siRNAs) or precursors without double-stranded character (piRNAs).
